About Provocholine

Sensitive

The Provocholine (methacholine chloride USP) challenge is highly sensitive, and the results are highly accurate. The low incidence of false-negative or false-positive results with Provocholine is due to the specificity of cholinergic stimulation as well as to the precision in preparing reagent dosages. A negative Methacholine Challenge Test rules out asthma with reasonable certainly in patients.

Reliable

Provocholine is standardized for reliability, with premeasured quantity and consistent quality. The need to weigh out bulk methacholine, a highly hygroscopic agent, is therefore eliminated.

Reproducible

Because of consistent quantity and quality, Provocholine delivers reproducible results.

Rapid Results

Starting with a premeasured vial of powder, serial dilutions can be made quickly with sterile normal saline (0.9% sodium chloride for injection) containing 0.4% phenol (pH 7.0 or with sterile normal saline 0.9% sodium chloride for injection). The Provocholine challenge provides rapid results, with FEV1 measurements within five minutes after each challenge concentration.
